Solved Grub access bhyve-Linux machine

kr0m

kr0m

I have a bhyve Linux virtual machine and I'm trying to test another kernel image, but it always boots with the same image.
I would like to access Grub boot menu in order to select the correct boot entry, but bhyve VM boot doesn't seem to display any Grub, it boots directly.
I have tested cloud image and ISO disk installation methods and grub/uefi loaders, all of them behave same way.

By the way I'm using vm-bhyve as virtual machine manager.

Any idea of how can I access grub menu on VM?

Best regards.
